Since each serves a different purpose, theories cannot become
laws. Explaining how or why a natural phenomenon occurs is what the set of ideas
called theories do. On the other hand, mathematical relationships that
describes what happens are what is done by laws.
Let me show an example that illustrates the points.
Describing what happens in the natural world are done by the mathematical
formulas called the Gas Laws. In this example, it would show that by using the
Gas Laws, I will be able to predict with great accuracy the pressure if I
double the temperature of a sealed gas. This idea is a law since the
relationship is mathematical and it tells us what will happen.
<span>On the other hand, in order to explain why gases behave like
the way they do, we must use the kinetic molecular theory.</span>
Answer:
14.3
Explanation:
The distance s as a function of time can be written as:
The rate of change is the derivative of d with respect to time:
The time t when the track has been traveling for 81 miles is given by:
Using t in the previous equation gives:
Gold and copper are less reactive than Hydrogen.
Hydrogen is less reactive than tin. This means that tin is more reactive than Gold and Copper.
<span>Calcium and Aluminum are the one reactive than tin.</span>
460 meters per second, or about 1,000miles per hour.
